I read the tutorial form user guide in starccm+ named Complex Chemistry: Hydrogen. I tried to analyse Methane reacting with air as the same way as this tutorial. I imported case from starccm+ library called Methane 17 species skeletal but I cannot get a reasonable result. My result showed there is no reaction in the tube. Can anyone teach me how to solve this problem? I will appreciate it if you can give me some useful suggestion.
